Materials/Concrete

Systematic Testing and Inspection of construction practices & materials utilized during construction, will ensure that your project specifications and sustainability goals are met.

Geotechnical & Background Characterization

Our Geo Technical Physical Sampling and Testing Team can be contracted to conduct on-site field sampling procedures, analysis of soils, aggregates, etc. , and take core samples of such mediums to evaluate, characterize materials for reuse or disposal purposes and install shallow ground water monitoring wells.

Construction and Reclamation site services

Sub-Base Construction/ Field & Lab Compaction Services
HawkMtn Labs is capable of analyzing site materials for suitability in accordance with your quality control plans, then performing quality assurance services on site as your project progresses.

concrete testing  2On-site soil testing for compaction and moisture is conducted using Troxler moisture density gauges. Dual Mass Dynamic Cone Penetrometers are used to determine bearing capacity of footers and other load bearing locations. Data from these tests are downloaded directly from the Troxler ™ gauge into our database, thus ensuring nearly error free reporting.

If further site investigations are required, HML can provide testing of runoff water for suitability in compliance with local codes and other similar services. HML can also provide coring and drilling services with our Track GeoProbe™ DPT Rigs. Our lab can also provide testing of reclamation materials to ensure compliance with permit limits for various elements.
